Mr Cameron, don’t take your ball home

as a leader you state your opinions, share your reasons and fight for what you believe in. As a leader of this country, this is the time to honour the decision the people have made, and despite that being different from what you wanted, it is still your country.
When playing in a team, no matter if the strategy is different than what you proposed, you play your part. Different viewpoints are great, and you don’t take your ball and go home if your strategy doesn’t win. You play your part as well as you can, with the team that you’ve got.
